分形理论在植物形态模拟中的应用

在虚拟植物生长建模的可视化研究中,分形是其重要的理论基础。它利用自然景物本身存在的自相似性,通过多种分形造型方法对自然实体进行建模。根据植物形态学原理和计算机图形学技术,采用分形方法可绘制出形态逼真的植物。为此,介绍了分形的基本理论,并在VisualC++6.0中利用迭代法对几种经典的分形树进行了程序模拟;在此基础上,通过连续改变分形树的内部参数,模拟了植物的动态变化过程,产生计算机动画效果,有较强真实感。

Application of Fractal Methods in Plant Simulation

In the study of visualization of plant growth modeling,the fractal methods is significant theoretical basis. Using the inherent self-similarity of natural scenery,many natural entities can be modeled by a variety of fractal modeling methods. This paper briefly introduced the knowledge of fractal theory,and then several fractal trees had drawed by computer graphics program by using Visual C + + 6. 0 software. On this basis,the continuous change of the parameters of fractal trees can simulate the dynamic chan...
